To all whom (It mrty (BIIILGEIIL;

Be it known that 1, JOHN A."Jo1vns,'a citiresident of Cincinnati, county of Hamilton, State of Ohio,'have invented certain new and useful Improvements in Structural Rein- The object of my invention-is to provide a means for reinforcing concrete a amst both tensileand shearinglstresses whic secure an increased efficiency and -are made at an eco- This object I attain by the inwhichure 1 is a side elevation ofa stri of Fig. 2is a view, partially in secton, of a reinforced concrete beam and partially in side elevation of the metal reinforce with the conone-e'nd ,of a bar slitted and the other ex-" end ofwhich a series of longitudinal slits a/ are made, each'successive sl t, counting fronf the bottom,being made at a greater distance 1 Specification of Letters Patent.

After the member has been so slitted it is laterally expanded, which causes the slits to take the 35 material between-the shts to form inclined "truss members (1?; This metal reinforce is ,truss relative y to the concrete and increases the compressive resistance of 5c 'What'I claim is A truss member consistin of a strip of metal having had longitudina slits cut in its ends, the slits being cut atincreasing :distances from the ends and the lower edges of the'strip and'being thene'x anded to the beam.
